Treatment of renal sarcoidosis: is there a guideline? Overview of the different treatment options.

Sarcoidosis is a multisystem granulomatous disease of unknown aetiology characterized by the presence of noncaseating granulomas. It may affect any organ including the kidney. A disordered calcium metabolism is most often responsible for the development of renal failure. Granulomatous interstitial nephritis is the most typical histological finding, but it rarely leads to renal insufficiency. Since development of renal insufficiency in sarcoidosis is uncommon, we lack large (randomized) trials concerning the treatment of this disorder. We gather most information from case reports and small series. Our knowledge of pulmonary sarcoidosis is more comprehensive. It is, however, impossible to treat renal manifestations identically because some of the drugs used in pulmonary sarcoidosis are nephrotoxic. Moreover, renal sarcoidosis is a specific entity with its own characteristics and response to therapy. A guideline for treatment is currently missing. Based on a review of the literature, we present an overview of the different treatment options to promote a more uniform and scrutinized approach of this disease. Hypercalcaemia and hypercalciuria can be treated with corticosteroids, (hydroxy)chloroquine or ketoconazole. Preventive measures play a supportive role. In granulomatous interstitial nephritis, glucocorticoids are the standard of care. In patients with failure of or a contraindication to corticosteroids or in those patients who need a high maintenance dose of corticosteroids, azathioprine or mycophenolate mofetil can be used. TNF-alpha inhibitors are useful in case of steroid-resistant sarcoidosis or in patients who develop severe steroid toxicity. With increasing insight in the pathogenesis of sarcoidosis, other immunosuppressive drugs have been proposed, but more research is necessary before their routine use can be advocated.

Mental Health and Quality of Life among Patients with Cancer during the SARS-CoV-2 Pandemic: Results from the Longitudinal ONCOVID Survey Study.

PURPOSE: This longitudinal survey study aimed to investigate the self-reported outcome measures of COVID-19 peritraumatic distress, depression, anxiety, stress, quality of life (QOL), and their associated factors in a cohort of cancer patients treated at a tertiary care hospital during the SARS-CoV-2 pandemic. METHODS: Surveys were administered at four time points between 1 April 2020 and 18 September 2020. The surveys included the CPDI, DASS-21, and WHOQOL-BREF questionnaires. RESULTS: Survey response rates were high (61.0% to 79.1%). Among the 355 participants, 71.3% were female, and the median age was 62.2 years (IQR, 53.9 to 69.1). The majority (78.6%) were treated with palliative intention. An important proportion of the participants reported symptoms of COVID-19 peritraumatic distress (34.2% to 39.6%), depression (27.6% to 33.5%), anxiety (24.9% to 32.7%), and stress (11.4% to 15.7%) at any time point during the study period. We did not find clinically meaningful mental health and QOL differences during the study period, with remarkably little change in between the pandemic's first and second wave. We found no consistent correlates of mental health or QOL scores, including cancer type, therapy intention, and sociodemographic information. CONCLUSION: This cohort of cancer patients showed considerable resilience against mental health and QOL deterioration during the SARS-CoV-2 pandemic.

Safety of pre- or postoperative accelerated radiotherapy in 5 fractions: A randomized pilot trial.

OBJECTIVE: Neo-adjuvant radiotherapy (NART) for breast cancer has shown promising survival results in retrospective trials. However, there are some obstacles such as a chemotherapy delay, an increased overall treatment time (OTT) and the risk of increasing surgical morbidity. Accelerated radiotherapy (RT) in 5 fractions allows to deliver NART in a very short time span and minimizes the delay of surgery and chemotherapy. This trial investigates this NART schedule for safety, feasibility and OTT. MATERIAL AND METHODS: Twenty patients eligible for neo-adjuvant chemotherapy (NACT) and breast conserving surgery, were randomized between NART before NACT or NACT and postoperative RT. In both arms, RT treatment was given in 5 fractions to the whole breast with a simultaneously integrated boost (SIB) on the tumor(bed). Lymph node irradiation was given concomitantly in case of lymph node involvement. OTT was defined as the time from diagnosis to last surgery in the intervention group, while in the control group the time between diagnosis and last RT-fraction was used. In the intervention group NACT-delay was defined as time between diagnosis and start of chemotherapy. RESULTS: 20 patients were included, and 19 patients completed treatment. OTT was significantly shorter in the intervention group (mean 218 days, range 196-253) compared to the control group (mean 237, range 211-268, p = 0.001). The difference in mean duration from diagnosis to the first treatment was a non-significant 4 days longer (31 vs 27 days, p = 0.28), but the start of NACT after diagnosis was delayed by 21 days (48 vs 27 days, p < 0.001). NART did not result in additional surgery complications. CONCLUSION: This pilot trial is the first to report on accelerated NART in 5 fractions with SIB. NART before NACT resulted in a shorter OTT with good safety results.
